A measure that would mandate guard rails on truck trailers is making its way through the House and Senate. These underride guard rails would prevent cars from sliding underneath semi trucks, and would significantly reduce the amount of deaths from collisions with truck trailers. The act was introduced by Senator Gillibrand (D) of New York and Senator Rubio (R) of Florida, and the bipartisan measure is likely to pass without much push-back from Congress.
The law would require guards to be fitted to the side of trailers, as well as the front of the truck. As of now, both of these are optional. The bill also requires stronger rear guards, which have been mandatory since the mid-1950s. These guard rails are a simple solution to a big problem– the Insurance Institute for Highway Safety estimates that a little under 1,500 people die every year as a result of collisions with semis, but does not specifically state which of those were from the vehicle sliding under the trailer. In 2015, the National Highway Traffic Safety Administration published a proposal to upgrade current impact guards, but never followed through with the plan. They sought to align U.S. standards with those in place in Canada, which are much more stringent. Their ultimate aim is to make these kinds of crashes less fatal, if not less common overall.
The new bill proposes that rear and side guards must be able to withstand an impact from a vehicle going at least 35 MPH, and would apply to truck trailers, and single-units that weigh 10,000 pounds or more.
Many tests have been conducted to prove that these panels will be able to withstand that kind of force. The manufacturer of the panels does not yet make the front panels, but is in the process of developing them. The disadvantage, however, is the cost. Two panels will put buyers back $3,000-$4,000. They also weight up to 800 pounds, which can slow down trucks and weaken the trailers.
